Embodiment 1
[0028] According to the formula of polycarboxylate three-high mother liquor, including 34 parts of methallyl polyoxyethylene ether, 4 parts of acrylic acid, 0.55 parts of sodium hypophosphite, 0.25 parts of 30% hydrogen peroxide, 0.15 parts of ammonium persulfate, 0.14 parts of vitamin C, 61.6 parts of deionized water. Mix water and polyether superplasticizer macromonomer evenly; heat up the base material; put hydrogen peroxide into the base material, put sodium phosphate and ammonium persulfate into the base material again, add acrylic acid and vitamin C to dissolve in water respectively to obtain dripping material ; drop the dripping material into the heated bottom material respectively, carry out the heat preservation reaction, add water and dilute to obtain the polycarboxylic acid mother liquor, and store it further.
Embodiment 2
[0030] According to the formula of polycarboxylate three-high mother liquor, including 31 parts of methallyl polyoxyethylene ether, 4.8 parts of acrylic acid, 0.6 parts of sodium hypophosphite, 0.4 parts of 30% hydrogen peroxide, 0.1 parts of ammonium persulfate, 0.15 parts of vitamin C, 61 parts of deionized water. Mix water and polyether superplasticizer macromonomer evenly; heat up the base material; put hydrogen peroxide into the base material, put sodium phosphate and ammonium persulfate into the base material again, add acrylic acid and vitamin C to dissolve in water respectively to obtain dripping material ; drop the dripping material into the heated bottom material respectively, carry out the heat preservation reaction, add water and dilute to obtain the polycarboxylic acid mother liquor, and store it further.
Embodiment 3
[0032] According to the formula of polycarboxylate three-high mother liquor, including 33 parts of methallyl polyoxyethylene ether, 4.5 parts of acrylic acid, 0.6 parts of sodium hypophosphite, 0.3 parts of 30% hydrogen peroxide, 0.2 parts of ammonium persulfate, 0.12 parts of vitamin C, 61.28 parts of deionized water.
